High-flow chemical corrosion resistant electric diaphragm pumps are available in single-acting and double-acting types, with specifications covering a variety of flow rates and pressures. They are commonly made of PVC, PTFE, or stainless steel and feature corrosion resistance, high flow rate delivery, stable operation, and easy maintenance.
The Stainless Steel high-power welded electric pneumatic diaphragm pump uses a motor or compressed air to drive a diaphragm in reciprocating motion to transport media. As the diaphragm moves back and forth, the pump chamber volume changes periodically, creating the suction and discharge processes. The media flows in only one direction under the action of a check valve, thus achieving continuous delivery. The diaphragm completely isolates the media from the drive components, preventing leakage and contamination. The welded pump body structure improves overall strength and sealing, making it suitable for conveying corrosive, high-viscosity, or particulate media, and offering excellent reliability in industrial and sanitary applications.

● The stainless steel sanitary double diaphragm pump adopts a dual-chamber structure, which automatically adjusts the internal pressure during the conveying process, reduces pulse fluctuations, and ensures flow stability.
● The stainless steel sanitary double diaphragm pump optimizes the flow channel through computational fluid dynamics (CFD), so that the fluid flows in the pump chamber with minimum resistance, reduces shear force, and ensures the integrity of sensitive materials.
● The micro-gap design between the valve ball and the valve seat of the stainless steel sanitary double diaphragm pump enables the valve ball to automatically adjust the sealing angle during operation, improve sealing performance, and reduce leakage.
● The stainless steel sanitary double diaphragm pump adopts a PTFE and EPDM composite diaphragm, the outer layer is corrosion-resistant, and the inner layer has enhanced elasticity. It can withstand high-frequency reciprocating motion, extend the life of the diaphragm, reduce the replacement frequency, and improve the long-term stability of the pump.
● The stainless steel sanitary double diaphragm pump adds a noise reduction buffer device in the pneumatic drive cavity, so that the compressed air forms a dispersed airflow when entering the pump body, reducing the airflow impact noise.
● When the internal pressure of the stainless steel sanitary double diaphragm pump increases abnormally, the built-in elastic pressure relief element will automatically release the excess pressure to prevent the pipeline or pump body from being damaged by overpressure.
Stainless steel high-power welded electric pneumatic diaphragm pumps are widely used in the chemical industry for conveying corrosive liquids and chemical raw materials, and also in the food and pharmaceutical industries for conveying slurries, additives, and cleaning solutions. Furthermore, in the environmental protection, water treatment, and electroplating industries, they can be used for the stable transport of wastewater, solid-containing media, or high-viscosity fluids, adapting to complex working conditions.
